以下は、プラットフォーム注意事項と変更事項です。
Platform notes:
* There are no binary packages for Microsoft Windows x64 Edition --
these will be provided in a future release.
* The RPM binary packages do not include the GUI bits.
* The Mac OS X binary packages are only provided as tarballs, there is no
installer for this release.
* There is no binary package for Mac OS X on 64-bit PowerPC because Apple
does not currently provide a 64-bit PowerPC version of iODBC.
* The HP-UX 11.23 IA64 binary package does not include the GUI bits because
of problems building Qt on that platform.
* The binary packages for Sun Solaris are only provided as tarballs, not
the PKG format, for this release.
* There are no binary packages for SCO OpenServer.
Changes since the last release:
Functionality added or changed:
* Added auto-reconnect option because automatic reconnect is now
disabled by default in libmysql
* Added auto is null option (Bug #10910)
* Added support for SQLMoreResults
* Checking SQL_ATTR_CONNECTION_DEAD now always calls mysql_ping() to
check for a dead connection.
* Remove ODBC escape syntax { and } that begin and terminate statements,
allowing {CALL (?)} for procedures that don't require OUT or INOUT
parameters
* Improved regression tests
* Added --with-separate-debug-driver ./configure option
Bugs fixed:
* SQL_ATTR_CONNECTION_TIMEOUT was inappropriately mapped to
MYSQL_OPT_CONNECT_TIMEOUT. (Bug #19823)
* Prepared statements using the embedded MySQL server would fail
due to an unitialized variable. (Bug #16535)
* Fix positioned update and delete on statements derived from one
table with no primary key but including all columns (Bug #22796)
* Only initialize the ODBC version when the old-style SQLAllocEnv()
is called. If SQLAllocHandle() is used, the ODBC version must be
explicitly specified using a call to SQLSetEnvAttr()
* On 64-bit systems, some types would be incorrectly returned. (Bug #26024)
* Using DataAdapter, Connector/ODBC may continually consume memory when
reading the same records within a loop (Windows Server 2003 SP1/SP2 only).
(Bug #20459)
* Fix truncation of queries with leading spaces when SQL_ATTR_MAX_ROWS
is set to a non-zero value (Bug #6609)
* Fixed problem with memory allocation in Windows for BLOB and long
queries that need re-allocation of net->buff
* Using Connector/ODBC, with SQLBindCol and binding the length to the return
value from SQL_LEN_DATA_AT_EXEC fails with a memory allocation error.
(Bug #20547)
* Fixed Windows-specific problems with the GUI for SQL_DRIVER_PROMPT
* Fixed issues with numeric and decimal rounding
* Fixed memory leak in SQLDriverConnect()
* Fixed serious memory leak in SQLSpecialColumns() (up to 8KB/call)
* Fixed handle leak in LibMain (Bug #21385, thanks to Leandro Becker)
* Fixed field lengths reported by SQLDescribeCol() when using functions
such as COMPRESS() in SELECT queries (Bug #20208)
* Fixed 64-bit issues related to SQLINTEGER columns defined as int,
but later cast to long.
* TIME fields were incorrectly converted into date/time values. (Bug #25846,
Bug #24867, and Bug #25432)
* Fixed #Deleted issue in Microsoft Access by changing the default behavior
of MyODBC driver regarding SQL_AUTO_IS_NULL variable. Added new option to
the GUI and driver
* Fixed memory leak in SQLSpecialColumns()
* Corrected return size of SQLGetStmtAttr() when getting desc handles
* Fixed SQLGetInfo() of SQL_TXN_CAPABLE to return SQL_TC_DDL_COMMIT
* For SQL_C_TIME, handle conversion from the different time-related MySQL
types, instead of always assuming it is just a TIME. (DATETIME, TIMESTAMP,
and DATE were all handled incorrectly.)
* Fix crash when default database is not set
* Fix handling of lost connections (Bug #14639)
* File DSNs could not be saved. (Bug #12019)
* Nullability of auto_increment fields is incorrect. (Bug #10130)
* Connector/ODBC may insert the wrong parameter values when using prepared
statements under 64-bit Linux. (Bug #22446)
* The SQLDriverConnect() ODBC method did not work with recent Connector/ODBC
releases. (Bug #12393)
* Some properties returned by SQLGetInfo() were set using the wrong data
type, resulting in possible memory overruns. (Bug #20995)
* Ending a transaction using SQLEndTran() on a environment handle was
not supported. (Bug #21588)
